[movies]Starry Bulges Yield Secrets to Galaxy Growth - *Video Credit:* Bryan Preston, The Space Telescope Science Institute *Ground-Based Image Credit:* Allan Sandage (The Observatories of the Carnegie Institution of Washington) and John Bedke (Computer Sciences Corporation and the Space Telescope Science Institute) *WFPC2 and NICMOS Image Credit:* NASA [ http://www.nasa.gov/ ], ESA [ http://spacetelescope.org/ ], and Reynier Peletier (University of Nottingham, United Kingdom)
*Description*:> The ground-based image in visible light locates the hub area imaged with the Hubble Space Telescope. This barred galaxy feeds material into its hub igniting star birth. The Hubble NICMOS instrument penetrating beneath the dust reveals clusters of young stars.

*Description*: Astronomers have combined information from the NASA Hubble Space Telescope's visible- and infrared-light cameras to show the hearts of four spiral galaxies peppered with ancient populations of stars. The top row of pictures, taken by a ground-based telescope, represents complete views of each galaxy. The blue boxes outline the regions observed by the Hubble telescope. The bottom row represents composite pictures from Hubble's visible- and infrared-light cameras, the Wide Field and...

*Description*: This collage of images in visible and infrared light reveals how the barred spiral galaxy NGC 1365 is feeding material into its central region, igniting massive star birth and probably causing its bulge of stars to grow. The material also is fueling a black hole in the galaxy's core. A galaxy's bulge is a central, football-shaped structure composed of stars, gas, and dust. The black-and-white image in the center, taken by a ground-based telescope, displays the entire galaxy...
